5 Signs of a Food Intolerance in Dogs and What to Do Next
You're feeding your dog a high-quality food, but something seems off. They're scratching constantly, their digestion is inconsistent, or they just seem uncomfortable. Before you assume it's the season or a bug, consider this: your dog might have a food intolerance.
Unlike a true allergy (which involves the immune system), an intolerance is a digestive issue where your dog has difficulty processing a specific ingredient. It's surprisingly common, and the symptoms can be subtle. Let's decode the signals.
Sign 1: The Itch That Has No Season
-
What to look for: Chronic itching, licking paws, scooting, or recurrent ear infections. While often linked to environmental allergies, these symptoms that persist year-round can point to a food trigger.
-
Common Culprits: Beef, dairy, chicken, wheat.
Sign 2: The Unpredictable Tummy
-
What to look for: Frequent gas, bloating, intermittent diarrhea or soft stools, or occasional vomiting that isn't linked to eating something obviously bad.
-
Common Culprits: Often related to grains, certain proteins, or food additives/preservatives that irritate the gut lining.
Sign 3: Chronic Ear Inflammation
-
What to look for: Red, waxy, or smelly ears that need constant cleaning. Yeast and bacteria love to overgrow in the inflamed, warm environment that a food reaction can create in the ear canals.
-
Important Note: Always see your vet to treat the infection, but ask if a food component could be a contributing factor.

Sign 4: Poor Coat Condition
-
What to look for: A coat that's chronically dry, flaky, dull, or has patches of thinning hair. Nutrition is the foundation of skin and coat health.
-
The Connection: An inflammatory response in the gut can prevent proper absorption of the nutrients (like Omega-3s) essential for a healthy coat.
Sign 5: General "Unthriftiness"
-
What to look for: Low energy, seeming less playful, or just not having that characteristic "sparkle" despite a clean bill of health from the vet.
What to Do If You Suspect a Food Intolerance
Step 1: The Vet Visit is Essential.
Rule out parasites, infections, and other medical conditions. Your vet can help you design a proper elimination diet.
Step 2: Simplify the Diet.
This is where the principles behind Duke's Delights are crucial. An elimination diet involves feeding one novel protein and one novel carbohydrate for 8-12 weeks. Our Salmon Sweet Potato Delight is a perfect example of this simple formula.
Step 3: Audit the Treats (This is HUGE!).
Many dogs are technically on a limited-ingredient diet but are still given chews, biscuits, or training treats full of potential triggers. Every single thing they eat must be part of the trial.
"We created our single-protein treats like Salmon Sweet Potato for this very reason. When you're trying to solve a mystery, you need simple, predictable ingredients. Our treats let you keep rewarding your dog without ruining the detective work." – The Duke's Delights Team
Step 4: Reintroduce & Observe.
After symptoms resolve, you slowly reintroduce old foods one at a time to identify the trigger.
